no. 1 approach

[0062] 1. First embodiment: Two-liquid lamination of glass-like coating layer and betaine structure layer

[0063] (1-1. Composition)

[0064] FIG. 1 shows a hydrophilic antifouling coating structure 1 according to the first embodiment of the present invention. also, Figure 4~7 Shows the chemical state when each layer of the hydrophilic antifouling coating structure 1 is formed.

[0065] In FIG. 1( d ), reference numeral 10 is a base material made of resin such as ABS. In the present invention, application to a housing of a measuring device is the main purpose, but is not limited thereto. The measuring equipment includes: a pipe laser device for detecting whether multiple sewer pipes are arranged in a straight line, a rotating laser device for detecting indoor horizontal positions, etc., a GPS (Global Positioning System, Global Positioning System) main body, and a radio wave transmitting and receiving device. Antennas, scanners for detecting terrain information through dig...

no. 1 approach and no. 2 approach

[0100] (First Embodiment and Second Embodiment: Summary, Other Modifications)

[0101] The first embodiment and the second embodiment are particularly effective for resins that have few OH groups on the surface, are difficult to activate the surface, and are difficult to apply hydrophilic coating directly, unlike metals, glass, and the like. Such a resin is not particularly limited, but ABS commonly used in housings of measuring devices and other measuring devices is particularly preferable.

[0102] It should be noted that, in the first embodiment and the second embodiment, in the case where the substrate is rich in OH groups such as metal and glass, no etching components are required, and the OH groups of the glassy coating and the OH groups of the substrate Condensation occurs to chemically bond.

[0103] The glassy coating layer in the first embodiment of the present invention is preferably formed to a thickness of several hundred μm or less. The reason for this is that ...

no. 3 approach

[0114] 3. Third Embodiment: Single-liquid lamination of antifouling layer (paint part and betaine structure part)

[0115] (3-1. Composition)

[0116] Figure 10~11 It shows the chemical state when each layer of the antifouling coating structure 3 according to the third embodiment of the present invention is formed. In this embodiment, Figure 11 The reference numeral 30 may be the same resin substrate as that of the first embodiment. In addition, the reference numeral 30 may be a molded structure, and the single-liquid coating of the paint and the betaine structure part may be directly performed on these substrates. to set the antifouling layer.

[0117] In this embodiment, unlike the first embodiment and the second embodiment, it is characterized in that a glass-like coating is not provided, but a silver compound and A betaine structure that forms paints and hydrophilic antifouling coatings by one-liquid coating.

[0118] like Figure 11As shown, an antifouling layer 3...

Abstract

Provided is a hydrophilic antifouling coating structure which can be applied not only to metals but also to resin surfaces, and which has high durability. This hydrophilic antifouling coating structure is provided with a substrate layer, a glass-like coating layer provided on the substrate layer, and a betaine structure layer provided on the glass-like coating layer, and the glass-like coating layer and the betaine structure layer contain 1 mass% or more of silver ions. Based on the hydrophilic antifouling coating structure, a solvent containing silver ions and tetraalkoxysilane is applied tothe surface of a substrate, alkoxysilane is hydrolyzed to form a glasslike coating layer, a solvent containing silver ions and the betaine structure is applied to the glass-like coating, and a silaneportion of the betaine structure is hydrolyzed to form a betaine structure layer. In the method, a solvent containing silver ions, tetraalkoxysilane, and a betaine structure may also be applied in theform of a single liquid.

Description

technical field [0001] The present invention relates to techniques for improving the antifouling and antibacterial properties of the surface of articles containing resins, and in particular to a hydrophilic antifouling coating structure with antibacterial properties and a method for forming the same, and a case having a hydrophilic antifouling coating structure. measuring equipment. Background technique [0002] Measuring equipment such as rotating lasers used at construction sites and pipe lasers used at sewer pipe installation sites are used in harsh outdoor environments such as sewer pipes, so rainwater and other dirt, cement, dirt, etc. The problem of bacteria harmful to the human body adhering to the measurement equipment. [0003] When these dirt and bacteria are wiped off from the measuring device case, the dirt itself may be difficult to remove, or in the case of cement, scratches caused by particles may remain, or stains of components contained in the dirt may rema...
